LU BRICATOR ATTACH M'ENT.

SPECIFICATION forming part of Letters Patent No. 361,435, dated April19, 1887.

l Application filed February 11, 181%?. Serial No. 227,311. (No model.)

To all whom it may concern: y

Be it known that I, ELIJAH McCoY, of Detroit,county of`Wayne,State ofMichigan,have invented a new and useful Improvement in LubricatorAttachments; and I declare the'following to bea full, clear, and exactdescription of the same, such as will enable others skilled in the artto which it pertains to make and use it, reference being had to theaccompanying drawings, which form a part ofthis specifica tion.

My invention relates to an improved lubrieating attachment in connectionwith air-brake cylinders; and it consists ofthe devices and applianceshereinafter specified,and more particularly pointed out in the claims.

lIn the drawings, Figure 1 is a view inelevation showing the lubricatingdevice attached to the steam-pipe communicating with an airbrakecylinder. Fig. 2 is a separate view, partly in section, ofthe featuresembodying my improvement.

A represents any ordinary lubricator or oilreservoir.

B represents an air-brake cylinder; C, the steanrpipe communicating withthe boiler and said air-brake cylinder; and D is an oilgexit pipe,leading from the reservoir or lubricator A, and communicating with myimproved attachment, and thence to the said steam-pipe.

Heretofore, where a visible-feed'lubricator has been employed forlubricating the airbrake cylinders, it has been found necessary to keepon hand one or more blind-feed lubricators,77 for the reason thatshouldthe visi-` ble-feed glass be accidentally broken ,resort must be had tothe blind lubricator to takethe place of the visible-feed lubricatorsfor lubricating said cylinders until opportunity is affordedto replacesaid visible-feed glass.

The necessity heretofore existing of provid'- ing the blind lnbricatorin addition to the visible-feed lubricator for this purpose hasnecessitated a great increase of expense and much annoyance; and it isthe purpose of my present invention to provide an attachment to be1ocated in connection with the said steam-pipe, which shall dispensewith the necessity of this eXtra blind lubricator, and to provide asingle apparatus which shall take the place of the visiblefeedlubrioator and the blind lubrica- I carry out my inchamber maycommunicate through said hollow neck with the steam-pipe. The valveitself is constructed with a hollow stem, F', to communicate with thehollow neck of the oilvaporizing chamber when seated. The upper end ofsaid valve terminates in a slush-cup, F2, communication from said cupwith the passage in the hollow stem of the valve F being controlled by aT-valve, G. This valve G is ,eugagedlwith a screw-tapped case, G',within the said cup,said case being provided at its base with orifices gg',to facilitate the passage of oil from this said cup to the passage ofthe said valve-stem F. These -orices g g overcome the necessity ofcompletely removing the valve from said case to permit the passage ofoil from the said slush-cup into the hollow valve-stem F. As thusconstructed, the valve G need only be lifted from its seat to allow thedischarge of the oil from said cup. The oil from the oil-exit pipe-maycommunicate with the oil-vaporizing chamber in any desired Emannerwithout departing from the principle of my invention; but I prefer,however, to locate upon said vaporizing-chambera visible-feed glass, H,having proper connections at its base with the oil-exit pipe and at itsupper end with said vaporizing-chamber, so that the oil may pass fromthe oil-exit pipe up through the visible-feed glass H and into theoil-vaporizing chamber, and thence through the neck e in va- IOO thevalve G, oil from the slush-cup will find ready passage into thesteam-pipe to supply the necessary lubrication.

To operate the valve F, which is liable to become excessively heated, Iprefer to provide it with a handle, f2, of any suitable non-conductingmaterial, so that said valve may be readily operated by the bare hand.When it becomes necessary to cut off the feed from the oil-exit pipe,steam may be shut oii from the steam-pipe to permit the valve G to beopened and oil to be fed from the slush-cup.

This dev'ice is simple, economical, iiotlikely to get out of order, andwhen the air-brake mechanismisequipped therewith theengineer is alwaysprovided with readily operative means to insure the lubrication of theairbrake cylinders without the necessity, heretofore liable to arise, ofhaving to exchange lubiieators.

\Vhat I claim isl. In alubricating apparatus, the combination of asteam-pipe having in communication therewith au oil-cliamber, anoil-pipe coniniunicating with said chamber, a valve to control thecommunication of the chamber with said steam-pipe and provided with aslushcup arranged to communicate with said steampipe, and a valve tocontrol the communication of said slush-cup with the steam-pipe,substantially as described.

2. In a lubricating apparatus, the combination of a steam-pipe having incommunicatioii therewith an oil-chamber provided with a visible-feedglass, au oil-pipe communicating with said chamber through said glass, avalve to control the communication of said chamber with the steam-pipeand provided with a slush-cup communicating with said steampipc, and avalve to control the communication of said slush-cup with saidsteam-pipe, substantially as described.

3. In a lubricating apparatus, the combination of a steam-pipe having incommunication therewith an oil-chaiiiber provided with a visible-feedglass, an oil-feed pipe communicating with said chamber through saidglass, a valve to control the feed of oil from said oilpipe through saidglass, a valve in said chamber to control its communication with thesteam-pipe, and said valve having a slush-cup communicating with saidsteam-pipe and provided with a valve controlling its communication withsaid steam-pipe, substantially 'as described.

et. In a lubricating apparatus, the combi- 'tion therewith anoil-chamber, an oil-feed pipe communicating with said chamber, a valveto control the communication of said chamber with said steam-pipe, saidvalve constructed with a hollow stem to communicate with said steam-pipewhen seated and provided at its upper end with a slushcup communicatingwith said hollow-stein, a valve to control the communication of saidslush-cup with said stern, said cup provided with a screw-tapped case toreceive said valve, said case coustructed with one or more orifices atits base to permit the discharge of oil into the said stem when itsvalve is loosened from its seat, substantially as described.

6. The combination, in a lubricating apparatus for an air-brakecylinder, of asteampipe, au oil-chainber communicating with saidsteam-pipe, an oil-pipe leading from a lubricator or oil-reservoircommunicating with said chamber, a valve to control the communication ofsaid chamber with the steam-pipe and having a slushcup communicatingwith the steam-pipe and provided with a valve controlling itscommunication with said steam` pipe, substantially as described.

7. The combination, in a lubricator for an air-brake cylinder, of aconduit leading fioin the main lubricatoi', a visible -fecd glass,through which said conduit communicates with the airbrakecyliiider, avalve to control the communication of said conduit with said cylinder,and, in connection therewith, means for feeding oil to said cylinderwhen the supply is cut off from said conduit, substantially asdescribed.

In testimony whereof I sign this specification in the presence of twowitnesses.
